气相流约束调控微细水射流的数值仿真

Numerical Simulation of High Pressure Micro Water Jet Modulation with the Constraint of Gas Flow

针对高压微细水射流的喷嘴磨损严重和分辨率很难进一步提高的问题,给出了一种新的射流方案,即气相流约束调控下的微细水射流。通过数值模拟的方法,对该射流方案的射流过程进行研究,并得到了气相流约束下微细水射流的流场分布。研究结果表明,该射流方案是可行的,能有效地减小射流喷嘴的磨损,以及进一步提高微细水射流的分辨率。

The high pressure micro water jet nozzle is often seriously worn and its resolution is difficult to further improve.To address this problem,a new method of the micro water jet under the constraint of the gas flow was presented in this paper.Using numerical simulation,the process of the jet was explored and the flow field distribution of the micro water jet under the constraint of the gas flow was obtained.The results show that the scheme proposed was feasible,capable of reducing effectively the wearing of the jet nozzle and improving its resolution.
